Winston's new fresh and saltwater Boron II-MX series. The MX stands for maximum, as in maximum power, distance and fish fighting capabilities. The 4, 5 and 6-weights are slightly stiffer and faster than their Boron IIx counterparts; the 7 through 12-weights are true “cannons” that can handle sinking lines, big flies and adverse wind conditions. While all models feature faster actions and are capable of making long distance, 100+ foot casts, they will amaze you with their responsiveness and light weight. Whether you’re chucking 6'' long “grocery” flies or battling fly rod humbling winds, a Boron II-MX will get the job done.
